l-MPROVEMENT IN SEPARABLE BUTTONS.

Specification forming part of Letters Patent No. 219,369, datedSeptember 9, 1879 application file August 4, 1879. v

To all whom it may concern:

Be it known that I, WARREN G. SMITH, of New York, in the county of NewYork and State of New York, have invented a new and useful Improvementin Separable Buttons, which improvement is fully set forth in thefollowing specification and accompanying drawings.

My invention relates to that class of separable buttons and studs madeof two principal parts that can be adjusted and locked together. l

The accompanying drawings illustrate my improved device.

Figure 1 is a perspective view of my button closed. Fig. 2 is asectional view on the line as m. Fig. 3 is a detailed view of theseveral parts disconnected.

Similar letters of reference indicate like parts.

The front piece or disk, A, forming the main portion of the button, canbe made of any ornamental shape or design, or can be mounted with astone or setting.

The post 13 is hollow, and is of an oval oblong shape. At the upper partof either of its longer sides is a triangular slot, b. The post B issoldered to the inner lining of the front button, A, and at its upperend is. covered with a flat cap, 6, pierced with an elongatedquadrangular slot, 0, having central projections or notches c c.

In order that the sides of the hollow post may give and spring while thelocking projections of the blade (1 are passing within to engage withinthe slots 12, the connections with the lining of the button A and thecap 0 are made only at the short curves of the post, the intermediateflat sides being left free and disconnected, thus forming an openingboth at the upper and lower end of the post.

The shoe D is supplied with a post-blade, d, preferably pointed, andfirmly held in a perpendicular position nearly up to the inner side ofthe shoe D by means of a central forked pin, cl, which fits into agroove in the blade d. The pin slightly projects beyond the sides of thepost-blade, forming the small shoulders at d. of the disk A is'a smallsocket or thimble, a, forming a receptacle for the point of the blade d,serving to kee'p the several parts steady when adjusted.

Operation: The oval post B is passed through the button-hole of thegarment, and then the blade dis inserted within the slot 0 of the cap 0.It cannot be placed inside excepting when the extensions of the forkedpin 01 are brought within the projecting notches c c of the slot 0. Theshoe D is then turned half round until the shoulders-c of. the blade clreach and engage within the triangular slots b, thus formtheengaging-shoulders of the blade D fall' into the triangular notches inthe hollow post by a simple half-turn of the shoe, and the button isreadily separated by the same motion reversed by bringing the shouldersof the forked pin Within the lateral slots 0 c in the cap 0. p

'I am aware that separable buttons have been made heretofore with alocking device inserted and engaging within a hollow post, and I do notbroadly claim such locking device; but

Having now fully described my invention, what I claim is- 1. In aseparable button, the hollow post B, provided with triangular sideslots, b b, and a cap, 0, pierced with a slot, 0, and lateral ex tendingnotches c c, substantially as de scribed. I

2. In a separable button, a shoe, D having a post-blade, cl, kept inposition at right angles with the plane of the shoe by means of theforked pind, and having shoulders 61', substantially as described.

In the center of the lining 3. A separable button consisting of thewhole adapted to interlock and form a commaiu front A having a hollowoval post, B, plete button when adjusted for use, substansnpplied withtriangular locking-notches I) I), tially as described. and cap 0 piercedwith main slot 0 and later- 4 1 ally-extending slots 0 c, in combinationwith WARREN SMHH' the shoe D, carrying a blade-post, (I, havingWVituesses: shoulders 61', retained in position by means GEORGE J.SMITH, of the forked pin (1, having shoulders d, the W.
